c++: add extern declaration to the generated file
The extern declaration affects how the C++ compiler does name mangling of global
variables. With:
$ g++ -c -Wall -std=c++11 -o osx2win32.o osx2win32.cc
$ nm osx2win32.o | grep code_map_osx_to_win32
0000000000000000 B code_map_osx_to_win32
00000000000000a1 t _GLOBAL__sub_I_code_map_osx_to_win32
Without:
$ g++ -c -Wall -std=c++11 -o osx2win32.o osx2win32.cc
$ nm osx2win32.o | grep code_map_osx_to_win32
0000000000000000 b _ZL21code_map_osx_to_win32
Not that unlike C, without "extern" you get a local variable ("b"), while
"extern" is needed to get a global!
